Using authlogic with STI User models

Reported by German Monfort | June 18th, 2009 @ 02:48 AM

Using authlogic with models that extend the User class (using Single Table Inheritance)
seems to break things since you end up with nil objects for @current_user in your controllers

class User < ActiveRecord::Base
class NormalUser < User;end
class SpecialUser < User;end

Is it possible to use authlogic with STI?

    I'm not sure, but I dont think it would be difficult to support. What are the specific errors?

    I'm using authlogic with STI right now and everything seems to work fine under development, but when I run it in production mode and attempt to update a model, this is what I get:

    NoMethodError (undefined method `=' for #<Patient:0xb34032c>):
    authlogic (2.1.1) [v] lib/authlogic/acts_as_authentic/password.rb:229:in `send'
    authlogic (2.1.1) [v] lib/authlogic/acts_as_authentic/password.rb:229:in `password='

    Here's the current setup for the models:

    class User < ActiveRecord::Base
    class Patient < User;end
    class Doctor < User;end

    I looked at the password method, but I'm not sure what is happening or what to look for, is authlogic actually passing the whole model to the password method. Any help would be much appreciated.

    It looks like:


    Is returning nil. What does Patient.column_names return for you?

    Here's what it returns:

    >> Patient.column_names

      Patient Columns (3.2ms)   SHOW FIELDS FROM `users`
      => ["id", "login", "name", "email", "crypted_password", "salt", "created_at",   "updated_at", "remember_token", "remember_token_expires_at", "first_name", "last_name", "ssn", "address", "city", "state", "zip", "drivers_license", "home_phone", "cell_phone", "fax", "employer", "insurance_co", "insurance_type", "insurance_id", "allergies", "medications", "operations", "chronic_conditions", "family_history", "immunizations", "visits_count", "appointments_count", "login_count", "getting_started", "type"]
